Disallowed Types and Members in System.dll
SQL Server common language integration (CLR) programming disallows the use of a type or member that has a HostProtectionAttribute that specifies a System.Security.Permissions.HostProtectionResource enumeration with a value of ExternalProcessMgmt, ExternalThreading, MayLeakOnAbort, SecurityInfrastructure, SelfAffectingProcessMgmnt, SelfAffectingThreading, SharedState, Synchronization, or UI. The following table lists the members and types of the System.dll assembly whose Host Protection Attribute (HPA) values are disallowed.
Note
This list was generated from the supported assemblies. For more information, see Supported .NET Framework Libraries.
